Hi all!!
Imo this is not a 2♣-opener. You have exactly 9 playing tricks and need in a minor 9.5 tricks at least. You cannot make 5♦ without partner having 2 Quick-tricks in the blacks. I can't hard imagine a hand with partner, which makes 3NT and he passes 1♦. Perhaps QTxx,xxx,xx,QTxx and 3NT isn't sure.
So I think it is safe to open 1♦.
But what is your rebid after partner bids 1♥??
1) a faky 1♠ forcing but misdescribing
2) 3♦. Is that really forcing?
3) 3NT showing a long and strong minor, but you are open in both blacks. 3NT maybe down, while 6♦ makes opposite Axxx,QJxxx,xxx,x
Is this another hand which calls for playing a strong club system?
Looking forward your expert comments
cheers
Al
